The interior surface of the tubular .xertinn 11 at the bottom is provided with threads Z2 which allow the sectin tu be threaded into the threaded portion device, said inner tubular member having an aperture adjacent the lower end thereof, and a valve arranged to engage the seat above said opening whereby the air from the interior of said outer tubular member and the fuel are controlled simultaneously.

3. In a carbureter of the character described, a easing, a throttle valve arranged in said casing, a' spray device arranged in said casing with the upper end adjacent said throttle valve, and means for supplying `fuel oil to said spray device, said spray device comprising an outer tubular member open at the top and bottom, a feed member connected to the lower end of said outer tubular member for feeding oil thereto, an inner tubular member connected with said feed member adjacent the lower end, said inner tubular member being provided with apertures adjacent the lower member for the admission of fuel, and a valve seat through Whichsaid fuel is arranged to pass, said inner tubular member at the upper end being also formed with a cone-shaped structure for guiding the fuel from the outer tubular member at an angle as the same is dischargeda valve member adapted to be moved towal'd and from said seat for controlling the flow of oil into said inner tubular member, and a spray nozzle .mounted on said inner tubular member with the upper part spaced therefrom, "itaid spray nozzle being provided with slo7ts or openings whereby oil may pass from said inner tubular member to a nozzle, said spray nozzle being provided with an extension projecting an appreciable distance into said inner rtubular member. said spray device being also provided with a passageway extending through said extension and to the periphery of the upper palt of said spray nozzle, whereby a plurality of points of discharge are provided, said points of discharge being at different levels.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
